Binladin has issued 77,000 final exit visas to foreign workers so that they can leave Saudi Arabia, and is expected to lay off 12,000 of 17,000 Saudis in supervisory, administrative, engineering and management jobs...While Saudi construction companies regularly cut or expand their foreign staff in response to changing demand in the industry, they rarely lay off large numbers of Saudis, partly because it is legally difficult and expensive.
